Lanto Griffin told Brandt Snedeker to get off the back of a golf cart late Sunday and sit in the front seat.

Snedeker refused and told Griffin, "No way; get up there and sit down. You've been working hard all day."

It was true. Griffin, 29, had to work extra hard to claim the second annual Nashville Golf Open at Nashville Golf and Athletic Club.

He defeated Abraham Ancer in a playoff by sinking an 18-foot uphill birdie putt.

Snedeker, who was in the cart to take Griffin back to the victory celebration, presented the guitar trophy to Griffin back on the 18th green as darkness fell on the course.

It was the first win on the Web.com Tour for the lanky 6-foot-3 Griffin, a native of Mount Shasta, Calif., who pocketed $99,000.

He entered the tournament ranked 135th on the tour's money list with a total of just $11,651 in career earnings.

It provided Griffin with a jolt of confidence he sorely needed at this point in his career.

"I didn't know if I could win on Web; I haven't always been the nicest to myself out here," said Griffin, who turned pro in 2010. "I worked really hard to get on Web, but I had talked about doing something else next year if I didn't keep my card out here. With the win I know I can at least play on this tour next year."

The victory provided Griffin with an exempt status on the Web.com Tour for the remainder of this season and all of 2018.

"The rest of the year is just going to be a blast," Griffin said.

Griffin had to work hard for the win, not only to pull away from Ancer, who birdied four of the last six holes in regulation, but also because of two weather delays that lasted a total of four hours.

After Ancer missed the green Griffin used a 7-iron to put his tee shot 15 feet from pin. The ball then rolled away from the hole three feet after hitting the green.

Ancer chipped on to about two feet from the hole.

Griffin then dropped his putt in for birdie.

"It was getting dark, which made it kind of hard to read that putt," Griffin said. "That had to be one of the best putts I've hit under pressure. I had the same putt for eagle the day before and I made it."

Griffin had tied the course record with a 10-under 62 on Saturday, the same score Conrad Shindler had posted in Thursday's first round.

Griffin entered the final round tied for second with Adam Schenk at 12-under.

Ancer said the rain delays bothered him, so he was happy to be able to force the playoff.

"I'm pretty proud of the way I played today with the rain delays," said Ancer, who earned $59,400.. "Every time I came back (from a delay), I made a bogey. I was a little antsy. But I bounced back really well and made a great run at it. If you are going to lose, you like to lose to a birdie."
